export interface ITaskListItems {
  value: ITaskListItem[];
}
export interface ITaskListItem {
  Title: string;
}

In the HelloWorldWebPart class, remove the existing default row provided by the framework and add a new row to load the results. Also, we’ll call a
JavaScript method to load the data. The updated render method looks like

public render(): void {
    this.domElement.innerHTML = `
      <div class="${ styles.helloWorld }">
        <div class="${ styles.container }">
          <div class="${ styles.row }">
            <div class="${ styles.column }">
              <div id="taskListInfo" />
            </div>
          </div>
        </div>
      </div>`;

      this.loadTaskListInfoAsync();
  }

loadTaskListInfoAsync calls two helper methods

One to query the data
private getListData(): Promise {
return this.context.spHttpClient.get(this.context.pageContext.web.absoluteUrl + `/_api/web/lists/getByTitle('Tasks')/Items?$select=Title`, SPHttpClient.configurations.v1)
.then((response: SPHttpClientResponse) => {
return response.json();
});
}

and a method to load the data to the html

Ensure that you have started the server by running

gulp serve

Now if we navigate to the SharePoint Online workbench and add the webpart, we should see the list of items in the
Tasks list

{sharepoint online site url}/_layouts/15/workbench.aspx

Now we can see the SharePoint Framework SpFx example in the SharePoint online workbench.

Deploy the app

Now lets deploy our SharePoint Framework SpFx example to SharePoint online. Press Ctrl + C to stop the gulp serve

Under the config folder, check the package-solution.json file. You can change any of the parameters such as id,
name etc. You can leave it as defaults for now.

Now, we can package up the solution

gulp package-solution

which will create a package file

Now we can add this package to our app catalog(Admin center -> apps -> app catalog). If it’s the first time
you are accessing your SharePoint online tenant you need to create the app catalog for this tenant.

Once it is added to app catalog, it will list the app and error column should say something like ‘No errors’

Now, lets add the SharePoint Framework SpFx example to the dev site. navigate to the dev site and click the gear icon and ‘Add an app’ and select the hello world web part.

Ensure ‘gulp serve’ is running on your local machine again. Now you can go to any page in your site and add this web part.

Notice that we are still serving this app from local server. You might get an error if gulp serve is not running
locally.

Deploying the files to Office 365 tenant CDN

Now instead of serving the files locally, we can upload it or host it in the CDN which is given for free by
Microsoft. Let’s go ahead and upload our SharePoint Framework SpFx example package to Microsoft CDN.

First, ensure you have the latest SharePoint
Online Management Shell

Next, connect to your tenant admin site

Connect-SPOService -Url https://<yourtenant>-admin.sharepoint.com

Enable the public CDN for the tenant

Set-SPOTenantCdnEnabled -CdnType Public

Lets check the setting by running

Get-SPOTenantCdnOrigins -CdnType Public and we should get back

In the package-solution.json ensure that includeClientSideAssets is set to true.
Let’s package the solution

gulp bundle --shipgulp package-solution --ship and redeploy the package. If the previous local package is already present, it will ask to replace. Click on ‘Replace it’Now, if we refresh our page and go to the console window and check the Sources tab, we can see the files for the SharePoint Framework SpFx example are served
from a public cdn. You can now do a Ctrl + C to end the ‘gulp serve’ on your local machine. The web part will still
work! Congratulations! you have successfully deployed a SharePoint Framework SpFx web part to Office 365 and served the
required files from a public cdn.
